yIMPROVEMENT IN FLUTING-MACHINES.

PATENT 0E Specification forming part of Letters Patent No. 138,650, dated May 6, 1873; applicatio filed December 12, 1872. l

To all whom it may concern:

Be it known that I, EDGAR P. HOLLY, of the city of Lockport, in the county of Niagara and State of New York, have invented certain Improvements in Fluting-Machines, of which the following is a specification:

My invention relates, first, to the combination of the upper arm of the frame and the lower arm and a bolt forming a hinge-joint, so that the rollers can be separated to admit material; second, to the combination in a utingmachine of the cogged or iluting rollers and the arms of the machine and a movable clamp, so that the said rollers shall be capable of working over a surface much wider than their own length; third, to the combination of the lower arm of the frame and the clamp and blocks, by means of which the machine may be immovably secured in 4its position. j

Figure 1 is a side elevation embodying my invention. that end of the machine which is at the right hand in'Fig. l. Fig. 3 is a vertical transverse section, showing the frame, rollers, and their cavities.

In Fig. 1, A A is the frame of the machine.

It consists of two arms, made strong enough to resist the tendency to spring whenv subjected to necessary pressure. To one end of each arm at B B and E E are attached hollow cogged rollers, such as are now in use for similar purposes, the cavities and openings of which are shown by the dotted lines at B B. The parts of the frame B B project from either arm inwardly, and are bored to receive journals turned upon the rollers O C at D D. E E are pieces attached to the arms A A by the screws F F. These 4pieces project from the ends of the arms to the center of the rollers C O and then at right angles into the rollers. A hole is drilled through them which connects with the center of the cavity or hollow space in the rollers. This is to admit a probe by which the heating-iron is pushed out of the rollers. A small piece of rubber is insertedbetween the pieces E E and the arms, which assists in adjusting the rollers and in equalizing the pressure. The diameter Fig. 2 is an elevation, showing' of the openings is less than the d meter of the hollow spaces in the rollers. i his prevents the hot iron or ashes from w king out. The arms A A are made separately e nd longer than the rollers C C.' They are; `rilled at H and there fastened by a bolt, h, n. such a way as to form a hinge-joint, so -t the upper arm may be lifted by looseningl he clamp and the rollers separated to admitl The rollers are revolved by means o l and crank I I, which is of iron an y ble strength. This shaft passes tir ough the lower arm A at K, and is provid end with a crank. At the other en l is enlarged to t and close the ope 1 hollow space of the lower roller. l he journal of the lower roller passes throu j yondf the projection B, and has a receives the key placed on the en rgement of the shaft, as shown at g. The is thus formed by which the rollers The clamp a is movable, embraces l th arms, and is provided with a thumb-scr w, under which and resting on the top of j arm A is a spring, b. This clamp spring hold the arms in place and equalize he pressure. They can be shifted or rem` tween the inner ends of the roller; and the clamp, the arms A A being of n. desired length. t

The machine is fastened to the table by means of the clamp c" and the blo; l. d d. One of the blocks is laid on the the machine is then placed upon3 clamp is then brought over the a m. atits point of contact with the wood. j piece d is then placed underneath clamp; then by means of the scre at the lower end of the clamp, the machi fastened immovably to the table.

I claim as my invention 1. The combination, in a iiutingan hine, of the arms A A and the bolt E formin l a hinge= pace bejoint, substantially as and for the purpose frame and the clamp c and the blocks d d', herein set forth. substantially as and. for the purpose hereinbe- 2. The combination of the rollers C C, the fore set forth. arms A A, and the movable clamp a and the EDGAR P. HOLLY. spring bf, substantially as and for the purpose Attest: hereinbefore set forth. CHAS.

3. The combination of the lower arm of the S. H. FINN.
